Where is the "path = /sbin/scsi_id" line coming from? Other lines are missing.
Did you change anything in the code. It should look more like this:

  udev[25565]: match_rule: KERNEL matches
  udev[25565]: match_rule: check PROGRAM
  udev[25565]: execute_program: execute '/bin/false' with main argument
  udev[25565]: execute_program: result is ''
  udev[25565]: execute_program: exec program status 0x100
  udev[25565]: match_rule: PROGRAM returned nonzero
  udev[25565]: match_rule: try parent sysfs device

And please try to run scsi_id on the commandline if it works there.
